Plug device of bus duct

Abstract

The invention discloses a plug structure. The plug structure comprises a plug unit and a communication unit, wherein the plug unit comprises a plurality of plug pieces; front ends of the plug pieces are spaced from one another to form intervals; rear ends of the plug pieces are gathered to form a gathered part; the communication unit comprises communication assemblies and fixing assemblies; the communication assemblies are spaced from one another to form communication space and are fixed by the fixing assemblies; and the intervals are inserted in the communication space to form electric connection. Firstly, by a plug mode of adding conductor units and connection units, heating to cause insulation damage and even short circuit due to poor contact can be completely eradicated; secondly, by conductors which are guided out from the bus duct, a plug box device for a guide-out requirement of a load of equipment can be added on an optional guided-out section of the bus duct; and thirdly, by conductor connecting plates, contact area can be greatly increased, and then, electric energy loss is reduced.

Description

technical field [0001] The invention relates to the technical field of power transmission and distribution equipment, in particular to a fast and safe plug-in type bus duct plug-in device. Background technique [0002] In recent years, with the rapid development of modern science and technology, and the emergence of modern engineering facilities and equipment, the electricity consumption of all walks of life has increased rapidly, especially the emergence of many high-rise buildings and large workshops. Cables can no longer meet the requirements in large current transmission systems, and the parallel use of multiple cables has brought a lot of inconvenience to on-site installation and construction connections; plug-in busbar connectors emerged as a new type of distribution wire Compared with it, it fully demonstrates its superiority in high current transmission. At the same time, due to the adoption of new technology and new technology, it greatly reduces the contact resista...

Problems solved by technology

With the development of the electric power industry in the market, users have higher and higher requirements for the performance and appearance of such products, but there are hidden dangers in the structure design of the existing plug-in box, especially the safety during the use of the plug-in box. The fixing between the box and the busway is fixed with a pressure plate. The first is that the positioning is not accurate enough. The second is that the plug-in box is easy to slide down due to its own gravity and external force during use, resulting in deformation of the pins and accidents. ; At present, this structure needs to be changed so that there is a clear positioning between the busbar plug-in box and the busbar and the busway body can bear the weight of the plug-in box to ensure safe operation

[0004] The prior art also has the following problems: the number of ways to lead out the power disconnecting switch plug-in box is limited to the way of plugging and pulling out the claws and the way of binding conductors, wherein: (1) the plugging and pulling out of the claws is due to the contact surface of the busbar conductive body leading out the power supply It is too small and difficult to fix, which often leads to heat and high temperature at the pin position, resulting in insulation degradation and short circuit; (2) The design of the conductor lead-out binding structure cannot meet the needs of the owner to increase the lead-out plug-in box under normal power transmission operation (expandability) At the same time, it is not conducive to maintenance and repair, and the wiring work with the second measurement side requires the overall circuit power failure to increase the plug-in box or perform maintenance work; (3) All connections use a large number of screws to connect the phase sequence conductors, which is prone to accidents The risk of quality control arises, including the small phase sequence distance that leads to problems with insulation and withstand voltage
